All the write sized slots in all the right places. The Raw Backflip tray has super strong magnets that fix in place securely when in use or when packed up. The beautifully tooled bamboo is a wonderful surface to roll on. You’ll find a convenient home for all your tools, papers and plenty of space to roll on. The rolling tool is a genius design, combining a rolling crutch and a scoop all held magnetically in place on the tray.
